T all whom t "concern A Beit knownxthat I, SiLsfA.Y ASriiioiriiaivn,

21a citizen of the UnitedStates o-f America,

residing at Detroit,"in the county vof Wayne i and Stateof Michigan, 'have invented certain. "new and useful Improvements in Pumpsfor `llfotor-Vehiclea of which the following is a specification,` reference being `frelativeto its operating means". As shown in thispatentthe'pump is detachably con` nected to a'suitable support, as the front end bearing or transverse member of a chassis, consequently the pump supporting element ofthe chassis has a `Xed relation relative'to It has been themotor shaft of the vehicle. found among a largefnumber of types of motorfvehicle-thatthe relation between an consequentlyitwas necessary forme to devise some means by which an air pump, such i' as disclosed in `myprior patent, could be heldin operative relation to an engine shaft where the engine shaft and bearing were 4out of alinement or where theopening in the chassis element couldnot be employed as a bearing for the pump. In contradistinction to the manner of" supporting the air pump or attaching it to a chassis element as heretofore disclosed, I discovered that the air pump could just as well be supported solely by the engine shaft and some provision made for preventing bodily rotation of the pump when in actual operation.

To this end, I provide a pump shaft with a rigid and preferably integral coupling member which can be easily and quickly fitted over the end of an engine shaft whereby the pump may be driven thereby7 said member passing loosely through the opening in the chassis element, such as the frame cross member or in some instances through the opening in the radiator or other member, and being supported solely upon the end of the engine shaft.. 1 then provide novel means ror preventing the pump from bodily rotating, and such means is simply employed for this purpose, without necessarily supporting any part of the air pump. Therefore the air pump is solely supported by the engine shaft employed for operating the pump, and consequently can be used in connection with vehicles where it would be f p `1=U1vii `ronf Moron-VEHICLES.

Thelfpreseiit invention will be better un` derstood when reference is had to the drawings and the detail description thereof diss i closing the preferred embodiments of `my invention, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within i the scope of the appended claim.

Iiithe drawings, Figure 1 is an elevation of an air pump, a. portionofan engine shaft, a portion'of i a chassis, the latter being in section and a pump broken away and in portion of the section;

Fig. 2 is a plan view of the Samet.

Fig. .Lis a cross sectional view taken on the.. line IV-IV Vof Fig. 3; i

Figx `isa perspective view 0f a portion ofa pump ear; f T i Fig. 6 is a perspective view of the detaclied keeper;

The drawings show portions of amotor vehicle, as an engine or motor shaft 1 hav-` end thereof; a portion of` a radiator 3, and a chassis element, such as a transverse channel member 4- having an opening 15 in ap-"- proximate axial alinement and in proximity to the -outer end of the engine shaft 1, or in other forms of 'construction the-opening through which the starting crank for turning the engine shaft, may be in some other member of the chassis than the channel member as when said opening is in the body of the radiator.

Referring now to Figs. 1 to 6 inclusive, an air pump 6 is associated with the above elements, said air pump having a back plate 7 provided with a bushing 8 adapted to eX- tend into the opening 5 of the channel member 4'. The bushing 8 constitutes one of the bearings of a pump shaft and the rear end of said l,pump shaft terminates in a rigid and integral coupling socket 10, having the rear end thereof slotted, as at 12, whereby the coupling socket can be slipped on the end of the shaft 1 and placed in engagement with the pin 2 thereof for rotative continuity with the engine shaft. The outer end of the engine shaft and the coupling socket 10 are of sufficient length whereby after the air pump is placed in engagement ing a transverse pin 2 Vadjacent theV outer With the engine shaft said shaft constitutes the sole means of supporting said air pump and this constitutes an important feature of my invention.

It is now apparent that if the engine shaft 1 be driven, that the air pump Would be bodily rotated, and to prevent such movement of the air pump and permit the shaft 9 to perform its usual function in connection with the pump, I have devised means in connection with the plate 7 and the channel member 1 for holdin-g the pump practically stationary. Such means however does not constitute a support for the pump, as said pump is solely supported by the lengine shaft, `but simply maintains the pump in an `operative useful position. The channelmember 4, contiguous to the opening 5,hasopenings 13 to receive keepers in the form-off bushings 14C. The inner ends of the bushings are exteriorlyscrewedthreaded lto receive nuts `l5 and the outer ends olf said bushings terminate -in cylindrical heads 16 .having radially disposed grooves 17 in communication with the bores of said bushings.

Slidable #in `the keepers of the channel members are retaining members comprising pins 18 having the inner ends thereof .provided vvith abutments 19 for coiled compression springs 2O encircling theinner .ends of the pins 18, said springs holding the retaining members in a retracted position.

The outer ends of the pins 18 terminate in cranks 21 having finger pieces 22 and Vsaid cranks are `normally held in engagement'With the'heads 16 of the keepers and in the grooves 1.47 of said heads, thereby preventing rotation of the retaining member until the cranks 21 are removed from the grooves 17. The cranks 21 of the retaining members are adapted to engage bifurcated or slotted ears 23 forming the ends of the plate 7, and said ears have grooves 24C in communication with the slots thereof to receive 'the cranks 2l of the retaining members. By reference to Fig. 3 it Will be noted that the slots or bifurcations `of the ears 23 are of suflicient'size to receive :theretaining ymembers and Withfsaid vmembers in a lateral positiointheair @pump canbe easily placed-in Aan operative position relative to the engine shaft and then the retaining members swung to =vertical positions simply to prevent the ain pump from rotating. With the retaining members in unlocked positions there is suflicient .clearance between said `members and ears 23 rto .permit of the =air `pump being properly positioned on theenginewshaft, and such clearance emphasizes the fact that `the air pump is solely supported by its operating means.

that 'I claim is The combination with a chassis element having an opening and anuengine shaft op* posite said opening, y'of va pump :tletachably attachedto iand-supported `.upon the end of said shaft by means passing :loosely through said opening.
